Description

本発明は、乗用車等の車両の荷室の上部を覆うトノカバー装置に関する。   The present invention relates to a tonneau cover device that covers an upper part of a luggage compartment of a vehicle such as a passenger car.

ハッチバック構造の小型乗用車等の後部の荷室は、外部から荷室内を隠すために、トノカバーと呼ばれるカバー部材によって上部が覆われるようにされている。ハッチバック構造では、トノカバーの収納スペースがない、あるいは狭いので、トノカバーをシート状の構造とし、それを巻き取る構造が提案されている(例えば、特許文献1または2を参照)。   A rear luggage compartment such as a small passenger car having a hatchback structure is covered with a cover member called a tonneau cover in order to conceal the cargo compartment from the outside. In the hatchback structure, there is no storage space for the tonneau cover or it is narrow, so a structure has been proposed in which the tonneau cover has a sheet-like structure and is wound up (see, for example, Patent Document 1 or 2).

ところで、デザイン上の観点から小型乗用車の後部の形状は、丸みを帯びたものとされる傾向がある。この場合、荷室後方の壁面も丸みを帯びた形状(R形状)となるので、トノカバー後部の縁もそれに合わせた形状とする必要がある。   By the way, from the viewpoint of design, the shape of the rear part of a small passenger car tends to be rounded. In this case, since the wall surface behind the cargo compartment also has a rounded shape (R shape), the edge of the rear portion of the tonneau cover needs to be shaped accordingly.

しかしながら、トノカバーをシート部材で構成した場合、その後部をR形状とすると、トノカバーの展開(張った)状態において、後部の縁の部分が垂れ下がらないように支える構造に工夫が必要となる。ハッチバック構造の場合、後部のドアが後ろに跳ね上げ式に持ち上げられるので、後部のドアにトノカバーを係合させ、支える構造(例えば、後部ドア内側に引っ掛け、引っ張られる構造)は好ましくない。このため、トノカバーの後部をR形状とする場合には、R形状の部分を剛性のある板状部材で構成し、その他の部分をシート状の構造とし、トノカバーの展開状態を維持する構造が提案されている。この構造に関しては、例えば特許文献1や2に記載されている。   However, when the tonneau cover is composed of a sheet member, if the rear portion is formed in an R shape, it is necessary to devise a structure that supports the rear edge portion so that it does not hang down when the tonneau cover is expanded (stretched). In the case of the hatchback structure, since the rear door is lifted up in a rearward manner, a structure in which the tonneau cover is engaged with and supported by the rear door (for example, a structure that is hooked and pulled inside the rear door) is not preferable. For this reason, when the rear part of the tonneau cover has an R shape, a structure is proposed in which the R shape part is composed of a rigid plate-like member and the other part is a sheet-like structure to maintain the unfolded state of the tonneau cover. Has been. This structure is described in Patent Documents 1 and 2, for example.

特開2003−220888号公報(要約書)JP 2003-220888 A (Abstract) 特開2003−220889号公報(要約書)JP 2003-220889 A (Abstract)

しかしながら、特許文献1や2に記載された構造では、トノカバーのR形状の部分が剛性を有するので、その部分はシート部材のように巻き取ることができない。このため、トノカバーを畳んだ状態において、トノカバーのR形状の部分が荷室内に張り出すことになる。これは、荷室を狭くすることになり好ましくない。特に小型乗用車の場合、荷室が狭いので、この問題が顕在になる。また、特許文献1や2に記載された構造では、収納状態において、トノカバーの引き出し端が、引き出し方向から見て奥側(車体の内部方向の側)になるので、小柄の人が扱う場合等に収納状態におけるトノカバーの引き出し端に手が届きにくくなる場合あり、操作性が悪くなる場合があった。   However, in the structures described in Patent Documents 1 and 2, since the R-shaped portion of the tonneau cover has rigidity, the portion cannot be wound up like a sheet member. For this reason, in the state which folded the tonneau cover, the R-shaped part of the tonneau cover protrudes into the cargo compartment. This is not preferable because the cargo space is narrowed. In particular, in the case of a small passenger car, this problem becomes apparent because the luggage compartment is narrow. Further, in the structure described in Patent Documents 1 and 2, in the housed state, the drawer end of the tonneau cover is on the back side (side in the interior direction of the vehicle body) when viewed from the drawer direction. In some cases, it is difficult to reach the drawer end of the tonneau cover in the storage state, and the operability may be deteriorated.

そこで本発明は、トノカバーの後部(車両の後部側)が丸みを有する構造において、展開時に丸みを有する構造部分を支えることができ、且つ折り畳んだ際に極力スペースを取らない構造とでき、さらに扱いやすい構造を提供することを目的とする。   Therefore, the present invention can support a structure portion having a roundness when unfolded in a structure in which the rear portion of the tonneau cover (the rear side of the vehicle) is rounded, and can take a space as little as possible when folded. The purpose is to provide an easy structure.

本発明の車両用トノカバー装置は、シート部材と、このシート部材を巻き取って収納する収納部と、シート部材の引出方向の縁に固定された第1の板状部材と、この第1の板状部材にヒンジを介し一方の辺が接続された第2の板状部材と、略同一面上に展開された第1の板状部材と第2の板状部材との展開状態を維持するための支持構造とを有し、第1の板状部材と第2の板状部材とは、第2の板状部材の下面を第1の板状部材の下面に重ね、且つ、第1の板状部材の上面を収納部の上面に重ねることで折り畳んで収納され、この折り畳み時において、第2の板状部材の他方の辺がシート部材の引き出し方向に位置することを特徴とする。   The vehicle tonneau cover device of the present invention includes a seat member, a storage portion that winds and stores the seat member, a first plate-like member fixed to an edge of the seat member in the pull-out direction, and the first plate. In order to maintain the unfolded state of the second plate member whose one side is connected to the plate member via a hinge, and the first plate member and the second plate member deployed on substantially the same plane The first plate-like member and the second plate-like member overlap the lower surface of the second plate-like member with the lower surface of the first plate-like member, and the first plate In this case, the other side of the second plate-shaped member is positioned in the pulling-out direction of the sheet member.

ここで、上面というのは、第1の板状部材および第2の板状部材を水平に展開した状態における鉛直方向上側の面のこといい、下面というのは、第1の板状部材および第2の板状部材を水平に展開した状態における鉛直方向下側の面のこという。なお、車体内部の意匠や構造によっては、第1の板状部材および第2の板状部材を展開しても、それが水平にならず、少し傾いた状態になる場合もあり得る。この場合は、展開状態において、鉛直方向上側に向いている面が上面、鉛直方向下側に向いている面が下面となる。   Here, the upper surface means the upper surface in the vertical direction in a state where the first plate member and the second plate member are deployed horizontally, and the lower surface means the first plate member and the first plate member. This is the surface on the lower side in the vertical direction when the two plate-like members are horizontally deployed. Depending on the design and structure inside the vehicle body, even if the first plate-like member and the second plate-like member are developed, they may not be horizontal and may be slightly inclined. In this case, in the unfolded state, the surface facing upward in the vertical direction is the upper surface, and the surface facing downward in the vertical direction is the lower surface.

この発明によれば、シート部材を巻き取って収納することで、トノカバーの収納スペースを小さくすることができる。また、シート部材の引出方向の縁に板状部材を固定することで、車体後部の形状に合わせてトノカバーの形状を決めることができる。また、トノカバーの収納時において、板状部材を折り畳み、それをシート部材の収納部の上に位置させることで、板状部材の収納スペースをコンパクトにすることができる。すなわち、本発明によれば、トノカバーの収納スペースを削減することができるので、荷室を広く利用することができる。   According to this invention, the storage space of the tonneau cover can be reduced by winding and storing the sheet member. Moreover, the shape of the tonneau cover can be determined according to the shape of the rear part of the vehicle body by fixing the plate-like member to the edge of the sheet member in the pull-out direction. Further, when the tonneau cover is stored, the plate-shaped member is folded and positioned on the storage portion of the sheet member, whereby the storage space for the plate-shaped member can be made compact. That is, according to the present invention, the storage space for the tonneau cover can be reduced, so that the luggage compartment can be widely used.

また本発明の車両用トノカバー装置は、第1のシート部材と、この第1のシート部材を巻き取って収納する収納部と、第1のシート部材の引出方向の縁に固定された第1の板状部材と、この第1の板状部材に第2のシート部材で構成されたヒンジを介して接続された第2の板状部材と、略同一面上に展開された第1の板状部材と第2の板状部材との展開状態を維持するための支持構造とを有し、第1の板状部材と第2の板状部材とは、第2の板状部材の下面を第1の板状部材の下面に重ね、且つ、第1の板状部材の上面を収納部の上面に重ねることで折り畳んで収納され、折り畳み時において、第2の板状部材の他方の辺が第1のシート部材の引き出し方向に位置することを特徴とする。   The tonneau cover device for a vehicle according to the present invention includes a first seat member, a storage portion for winding and storing the first seat member, and a first fixed to the edge of the first seat member in the pull-out direction. A plate-shaped member, a second plate-shaped member connected to the first plate-shaped member via a hinge constituted by a second sheet member, and a first plate-shaped developed substantially on the same plane And a support structure for maintaining the unfolded state of the member and the second plate-like member, and the first plate-like member and the second plate-like member are configured so that the lower surface of the second plate-like member is the first The first plate-shaped member is folded and stored by overlapping the lower surface of the first plate-shaped member and the upper surface of the first plate-shaped member is stacked on the upper surface of the storage unit. When folded, the other side of the second plate-shaped member is the first side. It is located in the pulling-out direction of the 1 sheet member.

この構成によれば、第1の板状部材と第2の板状部材とは、布や樹脂シートによって構成される第2のシート部材によって接続(連結)され、このシート部材が折れ曲がることでヒンジとしての機能が得られる。この構成は、例えば、第1の板状部材と第2の板状部材とを布等で覆い、周囲および折り目(両板状部材の接続部分)を縫製、溶着あるいは接着等によって固定することで得ることができる。この構造は、低コスト、高生産性、軽量、意匠性に優れるといった優位性がある。なお、第1のシート部材と第2のシート部材は、別材料であっても良いし、同一材料であってもよい。また、連続したシート部材を利用して第1のシート部材と第2のシート部材を構成しても良い。また上記第2のシート部材で構成されたヒンジの他に、第1の板状部材と第2の板状部材とを接続する他のヒンジを備えてもよい。 According to this configuration, the first plate-like member and the second plate-like member are connected (connected) by the second sheet member constituted by a cloth or a resin sheet, and the hinge is formed by bending the sheet member. The function as is obtained. In this configuration, for example, the first plate-like member and the second plate-like member are covered with a cloth or the like, and the periphery and the crease (the connection portion of both plate-like members) are fixed by sewing, welding, adhesion, or the like. Obtainable. This structure has advantages such as low cost, high productivity, light weight, and excellent design. The first sheet member and the second sheet member may be made of different materials or the same material. Moreover, you may comprise a 1st sheet member and a 2nd sheet member using a continuous sheet member. The other hinge constituted by the second sheet member may comprise other hinge connecting the first plate member and the second plate member.

本発明において、第2の板状部材の他方の辺には、握り部が配置されており、この握り部は、トノカバーを折り畳んだ状態において、シート部材の引き出し方向に位置することが望ましい。この態様によれば、トノカバーの収納時において、握り部は、引き出す手前側に位置するので、トノカバーの展開および収納の操作を行い易い。特に、トノカバーを折り畳んだ状態において、握り部が第2の板状部材における車体後方側に位置することになるので、ハッチバック構造のように車体の後方側からトノカバーの開閉操作を行う場合に、掴みやすい位置に握り部を位置させることができる。   In the present invention, a grip portion is disposed on the other side of the second plate-like member, and this grip portion is preferably located in the drawing direction of the sheet member when the tonneau cover is folded. According to this aspect, when the tonneau cover is stored, the grip portion is positioned on the near side to be pulled out, so that the tonneau cover can be easily expanded and stored. In particular, when the tonneau cover is folded, the grip portion is located on the rear side of the vehicle body in the second plate-like member. Therefore, when the tonneau cover is opened and closed from the rear side of the vehicle body as in the hatchback structure, The grip portion can be positioned at an easy position.

本発明は、車体後部の形状が丸みを帯びた車両への利用に適している。この場合、板状部材の引出方向の縁は、丸みを帯びた形状となる。板状部材の引出方向の縁が丸みを帯びた形状であっても、本発明では、板状部材の展開状態を維持するための支持構造を有しているので、展開状態にある板状部材が折れて垂れ下がる不都合を避けることができる。   The present invention is suitable for use in a vehicle having a rounded rear body shape. In this case, the edge in the drawing direction of the plate-like member has a rounded shape. Even if the edge in the pull-out direction of the plate member has a rounded shape, the present invention has a support structure for maintaining the expanded state of the plate member, so the plate member in the expanded state It is possible to avoid the inconvenience of being bent and drooping.

本発明において、板状部材の折り畳みは、ヒンジを用いて行われ、板状部材の展開状態を維持するための支持構造は、ヒンジが開いた状態を維持するロック機構であることが望ましい。この態様によれば、板状部材を折り畳んだ状態から展開すると、ヒンジの開状態がロックされ、板状部材の展開状態が維持される。これにより、展開した板状部材の垂れ下がりを防止することができる。   In the present invention, the plate-like member is folded using a hinge, and the support structure for maintaining the unfolded state of the plate-like member is preferably a lock mechanism that keeps the hinge open. According to this aspect, when the plate-shaped member is expanded from the folded state, the open state of the hinge is locked and the expanded state of the plate-shaped member is maintained. Thereby, it is possible to prevent the spread plate member from hanging down.

本発明において、板状部材の展開状態を維持するための支持構造として、第2の板状部材を下方から支える支持部材を備えた構造を採用することができる。この態様によれば、板状部材を展開した際に第2の板状部材が支持部材によって支えられ、その垂れ下がりが防止される。   In this invention, the structure provided with the supporting member which supports a 2nd plate-shaped member from the downward direction as a support structure for maintaining the expansion | deployment state of a plate-shaped member is employable. According to this aspect, when the plate-shaped member is developed, the second plate-shaped member is supported by the support member, and the sag is prevented.

本発明において、第1の板状部材および第2の板状部材の下面には、対となる面ファスナーが配置されており、これら板状部材を折り畳んだ状態において、この対となる面ファスナーを用いて、第1の板状部材と第2の板状部材とが接着されることが望ましい。この態様によれば、折り畳んだ状態における第1の板状部材と第2の板状部材とを簡単に固定することができ、またその固定状態の解除も簡単に行える。また、トノカバーを展開した状態で、面ファスナーが下面に位置するので、その存在が隠れ、意匠性を追究する上で有利となる。   In the present invention, a pair of hook-and-loop fasteners are arranged on the lower surfaces of the first plate-like member and the second plate-like member, and when the plate-like members are folded, the pair of hook-and-loop fasteners are arranged. It is desirable that the first plate member and the second plate member be bonded together. According to this aspect, the first plate-like member and the second plate-like member in the folded state can be easily fixed, and the fixed state can be easily released. Further, since the hook-and-loop fastener is located on the lower surface in the state in which the tonneau cover is unfolded, its presence is hidden, which is advantageous in pursuing design.

本発明によれば、トノカバーをシート部材と折り畳み可能な板状部材とで構成し、トノカバーを収納した際に、板状部材を折り畳んだものを、シート部材を巻き取った収納部の上に位置させる。これにより、トノカバーの後部(車両の後部側)が丸みを有する構造とでき、且つ折り畳んだ際に極力スペースを取らない構造とすることができる。また、折り畳んだ状態において、第2の板状部材の引き出し部分(引き出す縁の部分)を車体の後方側に位置させることができるので、トノカバーの収納および展開の操作を行いやすい構造を実現することができる。   According to the present invention, the tonneau cover is composed of a sheet member and a foldable plate member, and when the tonneau cover is stored, the folded plate member is positioned on the storage portion around which the sheet member is wound up.

The take-up shaft 109 is urged in the take-up direction by an urging means (not shown) so that the sheet member 102 can be taken up automatically. This biasing means is constituted by, for example, a torsion coil spring.

また、第1の板状部材103aの下面側と、第2の板状部材103bの下面側には、対となる面ファスナー110aおよび110bが配置され、第1の板状部材103aと第2の板状部材103bとを折り畳んだ際に、両者が面ファスナーによって接着されるようにされている。また、図1(C)に示すように、収納部107の上面両端には、係合部106が係合するフック111が配置され、板状部材103を折り畳んで収納する際に、係合部106をフック111に係合させ、それにより折り畳まれた板状部材103が収納部107上に固定されるようにされている。なお、図1(B)において、フック111は、図示省略されている。   Further, a pair of hook-and-loop fasteners 110a and 110b are arranged on the lower surface side of the first plate-like member 103a and the lower surface side of the second plate-like member 103b, and the first plate-like member 103a and the second plate-like member 103b are arranged. When the plate-like member 103b is folded, both are bonded by a hook-and-loop fastener. Further, as shown in FIG. 1 (C), hooks 111 that engage with the engaging portions 106 are arranged at both ends of the upper surface of the storage portion 107, and the engaging portions are folded when the plate-like member 103 is folded and stored. 106 is engaged with the hook 111, so that the folded plate-like member 103 is fixed on the storage portion 107. In FIG. 1B, the hook 111 is not shown.

また、板状部材103の他の構造として、図3に示す構造を挙げることができる。図3は、板状部材103の他の構造の一例を示す上面図(A)と側断面図(B)である。図3に示す構造では、第1の板状部材103aと第2の板状部材103bとは分離しておらず、第1の板状部材103aの骨となる板材33aと、第2の板状部材103bの骨となる板材33bとが布31によって覆われて、周囲および折り目34の部分で縫製されている。そして、折り目3の部分で折り曲げることができ、折り目3がヒンジとして機能する構造とされている。板状部材103の展開状態の維持は、図1と同様なヒンジ104によって実現される。ここでは、ヒンジ104として、後述する図7〜9に記載する構造が採用された場合の例が示されている。なお、布31を樹脂材料で構成し、縫製の代わりに布31を高周波ウェルダー等で溶着することもできる。また、縫製の代わりに布31を接着剤で接着してもよい。また、板材33aや33bは、ボール紙、ガラス繊維やPP(ポリプロピレン)繊維で補強されたもの等を利用して構成することができる。 As another structure of the plate-like member 103, a structure shown in FIG. FIG. 3 is a top view (A) and a sectional side view (B) showing another example of the structure of the plate-like member 103. In the structure shown in FIG. 3, the first plate-like member 103a and the second plate-like member 103b are not separated, and the plate member 33a that becomes the bone of the first plate-like member 103a and the second plate-like member The plate material 33b which becomes the bone of the member 103b is covered with the cloth 31, and is sewn at the periphery and the crease 34. Then, it is possible to bend the portion of the fold line 3 4, folds 3 4 is a structure that serves as a hinge. Maintenance of the unfolded state of the plate-like member 103 is realized by the hinge 104 similar to FIG. Here, an example in which the structure described in FIGS. 7 to 9 described later is adopted as the hinge 104 is shown. The cloth 31 may be made of a resin material, and the cloth 31 may be welded with a high-frequency welder or the like instead of sewing. Moreover, you may adhere | attach the cloth 31 with an adhesive agent instead of sewing. The plate members 33a and 33b can be configured using cardboard, glass fiber, PP (polypropylene) fiber, or the like.

(基本的な動作)
まず図1(B)がトノカバー101の収納状態である。収納状態において、シート部材102が収納部107の内部に巻き取られている。そして、板状部材103は、折り畳まれ、その折り畳まれたものが収納部107の上に置かれている。折り畳まれた板状部材103は、図1(C)に示すフック111、および面ファスナー110aと110bによって、収納部107上に固定されると共に折り畳まれた状態が維持されている。
(Basic operation)
First, FIG. 1B shows the storage state of the tonneau cover 101. In the stored state, the sheet member 102 is wound up inside the storage unit 107. The plate member 103 is folded, and the folded member is placed on the storage unit 107. The folded plate-like member 103 is fixed on the storage portion 107 and maintained in a folded state by the hook 111 and the hook-and-loop fasteners 110a and 110b shown in FIG.

図1(B)および図2(C)の収納状態において、車両の後方側から握り部105を手で握り、持ち上げると、面ファスナー110aおよび110bによって第1の板状部材103aに接着されていた第2の板状部材103bが外れる。そしてさらに握り部105を手前(車両の後方側、図1では矢印の方向)に引くと、図1(C)のフック111から係合部106が外れ、収納部107上に固定されていた第1の板状部材103aが収納部107から外れる。シート部材102は、図示しない付勢手段による付勢力によって収納部107内に巻き取られているので、握り部105をさらに引くと、板状部材103を平(水平)にしようとする力が働き、ヒンジ104が開く。ヒンジ104が開くと後述するロック機構の働きにより開いた状態がロックされ、板状部材103が開いた状態である程度の剛性を有したものとなる。   In the storage state of FIGS. 1B and 2C, when the grip portion 105 is grasped by hand from the rear side of the vehicle and lifted, it is adhered to the first plate-like member 103a by the hook-and-loop fasteners 110a and 110b. The second plate member 103b comes off. When the grip portion 105 is further pulled toward the front (rear side of the vehicle, in the direction of the arrow in FIG. 1), the engaging portion 106 is detached from the hook 111 in FIG. 1C and is fixed on the storage portion 107. One plate-like member 103 a is detached from the storage portion 107. Since the sheet member 102 is wound in the storage portion 107 by an urging force by an urging means (not shown), when the grip portion 105 is further pulled, a force to make the plate-like member 103 flat (horizontal) works. The hinge 104 opens. When the hinge 104 is opened, the opened state is locked by the action of a lock mechanism, which will be described later, and the plate member 103 is open and has a certain degree of rigidity.

そしてさらに握り部105を、巻き取りの付勢力に打ち勝つ力で引くと、収納部107内に巻き取られていたシート部材102が、引き出され展開される。そして、係合部106を図示しない被係合部に係合させ、展開状態を固定する(図2(A)の状態)。   When the grip portion 105 is further pulled with a force that overcomes the urging force of winding, the sheet member 102 that has been wound into the storage portion 107 is pulled out and deployed. And the engaging part 106 is engaged with the to-be-engaged part which is not shown in figure, and a deployment state is fixed (state of FIG. 2 (A)).

この状態でシート部材102は、収納部107側に引かれる付勢力によって張りが与えられ、荷室の上方を覆う。また、第1の板状部材103aは、収納部107の方向に巻き取りのための付勢力によって引っ張られ、また第1の板状部材103aは、図示しない車体側に水平に保持され、さらにヒンジ104は水平に開いた状態でロックされるので、第2の板状部材103bは、第1の板状部材103aと並んで水平な状態に維持される。つまり、板状部材103は、垂れ下がらず水平な状態で維持される。   In this state, the sheet member 102 is tensioned by an urging force drawn toward the storage unit 107 and covers the upper part of the cargo compartment. The first plate-like member 103a is pulled by the urging force for winding in the direction of the storage portion 107, and the first plate-like member 103a is held horizontally on the vehicle body (not shown) and further hinged. Since 104 is locked in a horizontally opened state, the second plate-like member 103b is maintained in a horizontal state along with the first plate-like member 103a. That is, the plate-like member 103 is maintained in a horizontal state without sagging.

トノカバー101を収納する際は、図1(A)に示す状態において、握り部105を握り少し引く、または少し引いて持ち上げる等の操作を行って係合部106の図示しない車体側への係合を解除する。シート部材102には、収納部107の方向に引っ張られる付勢力が作用しているから、上記の係合を解除した後に握り部105を握ったまま、車両の前方向(図1の矢印と逆方向)に握り部105を握った手を送ってゆくと、上記の付勢力によって、シート部材102が収納部107内に巻き取られてゆく。   When storing the tonneau cover 101, in the state shown in FIG. 1 (A), the grip portion 105 is gripped and pulled slightly, or slightly pulled and lifted to engage the engaging portion 106 to the vehicle body (not shown). Is released. Since the urging force pulled in the direction of the storage portion 107 acts on the seat member 102, the vehicle is moved in the forward direction (opposite to the arrow in FIG. 1) while holding the grip portion 105 after releasing the above-described engagement. When the hand gripping the grip portion 105 is sent in the direction), the sheet member 102 is wound into the storage portion 107 by the biasing force.

そして、シート部材102が収納部107内にそれ以上巻き取られなくなった時点で、図2(C)に示すようにヒンジ104を曲げて折り畳む。すなわち第1の板状部材103aと第2の板状部材103bとを山状(逆V字形状)に折り曲げ、両板状部材の下面同士を重ねた状態で折り畳む。そして、この折り畳んだものを後部座席114側に倒し(反転させ)、第2の板状部材103bの上面(図1(A)の状態における上側の面)を収納部107の上面に重ねる。この際、図1(C)のフック111に係合部106が嵌り、第1の板状部材103aが収納部107上に固定される。   Then, when the sheet member 102 is no longer wound in the storage portion 107, the hinge 104 is bent and folded as shown in FIG. That is, the first plate-like member 103a and the second plate-like member 103b are bent in a mountain shape (inverted V shape), and are folded in a state where the lower surfaces of both plate-like members are overlapped. Then, the folded product is tilted (reversed) toward the rear seat 114, and the upper surface of the second plate-like member 103 b (the upper surface in the state of FIG. 1A) is overlaid on the upper surface of the storage unit 107. At this time, the engaging portion 106 is fitted into the hook 111 in FIG. 1C, and the first plate-like member 103 a is fixed on the storage portion 107.

こうして図2(C)に示すトノカバー101の収納状態を得る。この際、第1の板状部材103a下面の面ファスナー110aと第2の板状部材103b下面の面ファスナー110bとが接触し、第1の板状部材103aと第2の板状部材103bとが折り畳まれて重なった状態で固定される。また、この折り畳まれた板状部材103がフック111に係合部106が係合することで、収納部107上に固定される。この状態において、第1の板状部材103aと第2の板状部材103bとは、第1の板状部材103aの下面を第2の板状部材103bの下面に重ね(対向させ)、且つ、第1の板状部材103aの上面を収納部107の上面に重ねることで折り畳まれている。この折り畳んで収納した状態において、第2の板状部材103bの他方の辺(握り部105が配置された側の辺)は、シート部材102の引き出し方向に位置する。なおここでは、展開状態において、第1の板状部材と第2の板状部材とが水平であり、同一平面内に平行に位置する例を説明したが、展開状態において、第1の板状部材と第2の板状部材とが、平行ではなく、少し折れ曲がっていてもよい。また、展開した状態において全体が少し傾いていてもよい。   In this way, the storage state of the tonneau cover 101 shown in FIG. At this time, the surface fastener 110a on the lower surface of the first plate member 103a and the surface fastener 110b on the lower surface of the second plate member 103b are in contact with each other, and the first plate member 103a and the second plate member 103b are in contact with each other. It is fixed in a folded and overlapping state. In addition, the folded plate-like member 103 is fixed on the storage portion 107 by the engagement portion 106 engaging with the hook 111. In this state, the first plate-like member 103a and the second plate-like member 103b are configured such that the lower surface of the first plate-like member 103a is overlaid (opposed) on the lower surface of the second plate-like member 103b, and The first plate member 103 a is folded by overlapping the upper surface of the storage unit 107. In the folded and stored state, the other side of the second plate-like member 103b (side on which the grip portion 105 is disposed) is positioned in the pulling-out direction of the sheet member 102. Here, an example has been described in which the first plate-like member and the second plate-like member are horizontal in the deployed state and are positioned in parallel in the same plane. The member and the second plate-like member may be bent slightly rather than in parallel. Moreover, the whole may incline a little in the expanded state.

(実施形態の優位性)
図1に示す構成によれば、荷室後部の構造が丸みを帯びた形状であっても、展開された状態がロックされる板状部材103により荷室の後部上方をトノカバー101によって覆うことができる。また、トノカバー101の収納状態において、シート部材102が収納部107内に巻き取られ収納され、さらに収納部107の上に折り畳まれた板状部材103が載せられた状態となるので、収納構造をコンパクトにすることができる。また、収納状態において、握り部105が車体の後方側にあるため、トノカバー101の展開操作や収納操作を行いやすく、使い勝手を良くすることができる。また、板状部材103の展開状態において、板状部材103の折り畳まれた状態を維持するための面ファスナー110aおよび110bが、板状部材103の下面側に位置するので、面ファスナーが人目に付き難く、デザイン性を追究することができる。
(Advantages of the embodiment)
According to the structure shown in FIG. 1, even if the structure of the rear part of the cargo compartment is rounded, the upper part of the rear part of the cargo compartment can be covered with the tonneau cover 101 by the plate-like member 103 that is locked in the unfolded state. it can. In the storage state of the tonneau cover 101, the sheet member 102 is wound and stored in the storage unit 107, and the folded plate member 103 is placed on the storage unit 107. It can be made compact. Further, since the grip portion 105 is on the rear side of the vehicle body in the storage state, the tonneau cover 101 can be easily unfolded and stored, and the usability can be improved. Further, since the hook-and-loop fasteners 110a and 110b for maintaining the folded state of the plate-like member 103 are located on the lower surface side of the plate-like member 103 in the unfolded state of the plate-like member 103, the hook-and-loop fastener is conspicuous. It is difficult to pursue design.

(ヒンジの構成1)
以下、ヒンジ104の幾つかの例を説明する。ここでは、主にヒンジを図1に示す板状部材103の連結に利用する場合を説明するが、以下に述べるヒンジは、図3に示す構造に利用することもできる。図4は、図1および図2に示すヒンジ104の他の一例を示す断面図である。図4には、第1の板状部材103aと第2の板状部材103bとを連結したヒンジ301が示されている。ここで、図4(A)には、板状部材が展開され(広げられ)、その展開状態を維持された状態(ロック状態)が示されている。また、図4(B)には、板状部材を折り畳むためにロック状態を解除し、折り曲げを行った状態が示されている。
(Hinge structure 1)
Hereinafter, some examples of the hinge 104 will be described. Here, the case where the hinge is mainly used for the connection of the plate-like member 103 shown in FIG. 1 will be described, but the hinge described below can also be used for the structure shown in FIG. FIG. 4 is a cross-sectional view showing another example of the hinge 104 shown in FIGS. 1 and 2. FIG. 4 shows a hinge 301 that connects the first plate member 103a and the second plate member 103b. Here, FIG. 4A shows a state where the plate-shaped member is expanded (expanded) and the expanded state is maintained (locked state). FIG. 4B shows a state where the locked state is released and the plate member is folded in order to fold the plate member.

ヒンジ301は、樹脂製であり、符号302の部分で図4(B)に示すように折り曲げることができる。この折り曲げは、樹脂材料の弾性により実現されている。ヒンジ301には、爪部303とこの爪部303に係合する突起部304が設けられている。ヒンジ301を閉じた状態(折り曲げた状態)から開く(折り曲げた状態から水平にする)と、爪部303が突起部304に引っ掛かり、両者が係合し、開いた状態がロックされる。爪部303および突起部404も樹脂材料で構成されているので、ヒンジ301を開いた状態において、折り曲げようとすると、ある程度の力が加わった際に上記の係合が外れ、図4(B)に示すようにヒンジ301を折り曲げることができる。   The hinge 301 is made of resin and can be bent at a portion indicated by reference numeral 302 as shown in FIG. This bending is realized by the elasticity of the resin material. The hinge 301 is provided with a claw portion 303 and a protrusion 304 that engages with the claw portion 303. When the hinge 301 is opened from the closed state (folded state) (from the folded state to the horizontal state), the claw portion 303 is hooked on the projection portion 304 and both are engaged, and the opened state is locked. Since the claw portion 303 and the projection portion 404 are also made of a resin material, when the hinge 301 is opened with the hinge 301 opened, the above engagement is released when a certain amount of force is applied, and FIG. The hinge 301 can be bent as shown in FIG.

(ヒンジの構成2)
図5は、図1のヒンジ104の他の一例である。図5に示すヒンジ400は、ヒンジ軸401によって連結された第1の部材402と第2の部材403を備える。第1の部材402は、第2の板状部材103bに固定され、第2の部材403は、第1の板状部材103aに固定されている。ここまでの構造は、通常の蝶番と同じである。
(Hinge structure 2)
FIG. 5 is another example of the hinge 104 of FIG. A hinge 400 shown in FIG. 5 includes a first member 402 and a second member 403 connected by a hinge shaft 401. The first member 402 is fixed to the second plate member 103b, and the second member 403 is fixed to the first plate member 103a. The structure so far is the same as a normal hinge.

図5に示すヒンジ400は、さらに第1の部材402が、断面形状が瘤状の圧入突起404を備え、第2の部材403が、この圧入突起404が嵌まり込む形状の凹型の受け部405を備えている。ここで、圧入突起404および/または受け部405は、多少変形する樹脂材料で構成されている。   In the hinge 400 shown in FIG. 5, the first member 402 further includes a press-fitting protrusion 404 having a knob-like cross-sectional shape, and the second member 403 has a concave receiving portion 405 in which the press-fitting protrusion 404 is fitted. It has. Here, the press-fitting protrusion 404 and / or the receiving portion 405 are made of a resin material that is somewhat deformed.

ヒンジ400を閉じた状態から開くと(折れた状態から水平にすると)、圧入突起404が受け部405の凹部内部に圧入され、第1の部材402と第2の部材403とが互いに固定される。この際、圧入突起404および/または受け部405が少し変形し、圧入突起404の受け部405の凹部内部への圧入が許容される。圧入突起404は受け部405に嵌まり込むので、両者の固定状態はロックされる。これにより、展開された板状部材103(図1参照)の形状を維持する剛性が確保される。   When the hinge 400 is opened from the closed state (when it is leveled from the folded state), the press-fitting projection 404 is press-fitted into the concave portion of the receiving portion 405, and the first member 402 and the second member 403 are fixed to each other. . At this time, the press-fitting protrusion 404 and / or the receiving part 405 is slightly deformed, and the press-fitting of the press-fitting protrusion 404 into the recess of the receiving part 405 is allowed. Since the press-fitting protrusion 404 is fitted into the receiving portion 405, the fixed state of both is locked. Thereby, the rigidity which maintains the shape of the expand | deployed plate-shaped member 103 (refer FIG. 1) is ensured.

また、少し力を入れて、ヒンジ400を折り曲げようとすると、圧入突起404が受け部405に嵌まり込んだ状態から外れ、ロック状態が解除され、第1の板状部材103aと第2の板状部材103bとを折り畳むことができる。   Further, when a little force is applied to try to bend the hinge 400, the press-fit projection 404 is released from the state of being fitted into the receiving portion 405, the locked state is released, and the first plate-like member 103a and the second plate are released. The shaped member 103b can be folded.

(ヒンジの構成3)
図6は、図1のヒンジ104の他の一例である。図6に示すヒンジ500は、ヒンジ軸501によって連結された第1の部材502と第2の部材503を備える。第1の部材502は、図示省略した第2の板状部材103b(図1参照)に固定され、第2の部材503は、図示省略した第1の板状部材103a(図1参照)に固定されている。ここまでの構造は、通常の蝶番と同じである。
(Hinge structure 3)
FIG. 6 is another example of the hinge 104 of FIG. A hinge 500 shown in FIG. 6 includes a first member 502 and a second member 503 connected by a hinge shaft 501. The first member 502 is fixed to the second plate-like member 103b (see FIG. 1) (not shown), and the second member 503 is fixed to the first plate-like member 103a (see FIG. 1) (not shown). Has been. The structure so far is the same as a normal hinge.

図6に示すヒンジ500は、ヒンジを構成する第2の部材503に押圧台座504を備えている。押圧台座504は、円筒形状の空間505を備え、そこにコイルばね506が収められている。円筒形状の空間505の一方の軸方向の端部は、ネジ止めされた蓋体507によって閉鎖され、他端には、コイルばね506によって外方向に付勢された金属ボール508が位置している。また、ヒンジを構成する第1の部材502の上記付勢された金属ボール508によって押される部分には、凹部509が形成されている。   A hinge 500 shown in FIG. 6 includes a pressing base 504 on a second member 503 constituting the hinge. The pressing base 504 includes a cylindrical space 505 in which a coil spring 506 is accommodated. One axial end of the cylindrical space 505 is closed by a screwed lid 507, and a metal ball 508 biased outward by a coil spring 506 is located at the other end. . A concave portion 509 is formed in a portion of the first member 502 constituting the hinge that is pressed by the biased metal ball 508.

図6に示すのは、ヒンジ500を開き、その状態がロックされた状態である。このロック状態は、金属ボール508が凹部509にコイルばね506の付勢力によって押し付けられることで実現される。ヒンジ500を折り曲げようと力を加えると、金属ボール508がコイルばね506を押して後退し、第1の部材502を第2の部材503に対してヒンジ軸501を軸として回転させることができる。これにより、折り畳みが行なわれる。   FIG. 6 shows a state in which the hinge 500 is opened and the state is locked. This locked state is realized by pressing the metal ball 508 against the recess 509 by the biasing force of the coil spring 506. When a force is applied to bend the hinge 500, the metal ball 508 pushes back the coil spring 506, and the first member 502 can be rotated with respect to the second member 503 about the hinge shaft 501. Thereby, folding is performed.

(ヒンジの構成4)
図7は、図1のヒンジ104の他の一例である。図7(A)は側面図、図7(B)および(C)は、軸に直交する方向で切った断面図である。図7に示すヒンジ600は、軸601とケース602を備えている。図7には図示省略されているが、軸601に折り畳み可能な板状部材の一方が固定され、ケース602に他方の板状部材が固定される。
(Hinge structure 4)
FIG. 7 is another example of the hinge 104 of FIG. 7A is a side view, and FIGS. 7B and 7C are cross-sectional views cut in a direction orthogonal to the axis. A hinge 600 shown in FIG. 7 includes a shaft 601 and a case 602. Although not shown in FIG. 7, one of the foldable plate members is fixed to the shaft 601, and the other plate member is fixed to the case 602.

ここで、図7(B)はロック状態を示し、図7(C)は、軸601を回転させている途中の状態を示す。軸601は、図7(B)に示されるように非円形な形状(この例では、レモンの断面形状型)を有している。また、ケース602の内側は、変形が可能な弾性材料(例えばゴム材料や樹脂材料)603が充填され、そこには軸601の断面形状に合わせた内部空間が設けられている。   Here, FIG. 7B shows a locked state, and FIG. 7C shows a state in the middle of rotating the shaft 601. As shown in FIG. 7B, the shaft 601 has a non-circular shape (in this example, a cross-sectional shape of lemon). The inside of the case 602 is filled with a deformable elastic material (for example, a rubber material or a resin material) 603, and an internal space corresponding to the cross-sectional shape of the shaft 601 is provided therein.

図7(B)の状態において、軸601は、弾性材料603に保持され、回転し難い状態(つまりロック状態)とされている。軸601をケース602に対して回転させようと力を加えると、ある程度力を加えた段階で弾性材料603が変形し、軸601が回転する(例えば図7(C)の状態)。この構成を利用することでも、図1の板状部材103の展開状態の維持(ロック)を実現することができる。   In the state of FIG. 7B, the shaft 601 is held by the elastic material 603 and is in a state where it is difficult to rotate (that is, a locked state). When a force is applied to rotate the shaft 601 with respect to the case 602, the elastic material 603 is deformed when the force is applied to some extent, and the shaft 601 rotates (for example, the state of FIG. 7C). By utilizing this configuration, it is possible to realize the maintenance (lock) of the unfolded state of the plate-like member 103 of FIG.

図8は、図1のヒンジ104の他の一例である。図8(A)は側面図、図8(B)および(C)は軸に直交する方向で切った断面図である。図8に示すヒンジ700は、軸701とケース702を備えている。図8には図示省略されているが、軸701に折り畳み可能な板状部材の一方が固定され、ケース702に他方の板状部材が固定される。
(Hinge structure 5)
FIG. 8 is another example of the hinge 104 of FIG. 8A is a side view, and FIGS. 8B and 8C are cross-sectional views cut in a direction perpendicular to the axis. A hinge 700 shown in FIG. 8 includes a shaft 701 and a case 702. Although not shown in FIG. 8, one of the foldable plate members is fixed to the shaft 701, and the other plate member is fixed to the case 702.

ここで、図8(B)はロック状態を示し、図8(C)は、軸701を回転させている途中の状態を示す。軸701は、図8(B)に示されるように非円形な形状(この例では、2方向(左右)に突出した凸部を有する断面形状)を有している。またケース702の内側は、軸701が回転可能な空間704を備えている。この空間704には、軸701の外形に対応した形状を有し、軸701を上下から押している一対の板ばね703が配置されている。   Here, FIG. 8B shows a locked state, and FIG. 8C shows a state in the middle of rotating the shaft 701. As shown in FIG. 8B, the shaft 701 has a non-circular shape (in this example, a cross-sectional shape having convex portions protruding in two directions (left and right)). The case 702 includes a space 704 in which the shaft 701 can rotate. In this space 704, a pair of leaf springs 703 having a shape corresponding to the outer shape of the shaft 701 and pressing the shaft 701 from above and below are arranged.

図8(B)の状態において、軸701は、板ばね703によって上下から押されている。この状態から軸701が回転しようとすると、軸01の両サイドの凸部が板ばね703を外側に押すので、回転するのに板ばね703を変形(変位)させる力が必要となる。この原理により、軸701が回転しないようにロックされた状態が実現されている。軸701をケース702に対して回転させようとある程度の力を加えると、軸701両サイドの凸部が板ばね703を押し、その付勢力に打ち勝って軸701が回転する(例えば図8(C)の状態)。この構成を利用することでも、図1の板状部材103の展開状態の維持(ロック)を実現することができる。 In the state of FIG. 8B, the shaft 701 is pushed from above and below by a leaf spring 703. When the shaft 701 from this state to rotate the convex portions on both sides of the shaft 7 01 because press the plate spring 703 outwardly, the force to deform the plate spring 703 to rotate (displace) is required. By this principle, a state where the shaft 701 is locked so as not to rotate is realized. When a certain amount of force is applied to rotate the shaft 701 with respect to the case 702, the convex portions on both sides of the shaft 701 push the leaf spring 703 and overcome the urging force to rotate the shaft 701 (for example, FIG. ) State). By utilizing this configuration, it is possible to realize the maintenance (lock) of the unfolded state of the plate-like member 103 of FIG.

(ヒンジの構成6)
図9は、図1のヒンジ104の他の一例である。図9(A)は上面図、図9(B)は図9(A)のヒンジ部分の断面図である。図9に示すヒンジ800は、第1の部材801と第2の部材802がヒンジ軸805を介して連結された構造を有している。
(Hinge structure 6)
FIG. 9 is another example of the hinge 104 of FIG. 9A is a top view, and FIG. 9B is a cross-sectional view of the hinge portion of FIG. 9A. A hinge 800 shown in FIG. 9 has a structure in which a first member 801 and a second member 802 are connected via a hinge shaft 805.

第1の部材801には、円筒部材803が固定され、円筒部材803は、ヒンジ軸805の外側に回転可能な状態で嵌め込まれている。また、第2の部材802には、円筒部材804が固定され、円筒部材804は、円筒部材803に隣接してヒンジ軸805の外側に回転可能な状態で嵌め込まれている。   A cylindrical member 803 is fixed to the first member 801, and the cylindrical member 803 is fitted on the outside of the hinge shaft 805 in a rotatable state. In addition, a cylindrical member 804 is fixed to the second member 802, and the cylindrical member 804 is fitted to the outside of the hinge shaft 805 adjacent to the cylindrical member 803 so as to be rotatable.

円筒部材803と804は、その外形よりも小さい内径を有するコイルばね806の内側に強制的に嵌め込まれている。また、コイルばね806は圧縮された状態で第1の部材801と第2の部材802との間に嵌め込まれている。   The cylindrical members 803 and 804 are forcibly fitted inside a coil spring 806 having an inner diameter smaller than the outer shape thereof. Further, the coil spring 806 is fitted between the first member 801 and the second member 802 in a compressed state.

この構造によれば、第1の部材801と第2の部材802とは、任意の開き角度でロックされる。すなわち、コイルばね806は、隣接する円筒部材803と804とを径方向の外側から締め付け、また第1の部材801と第2の部材802とを内側から外側に向かって付勢しているので、その締め付け力と付勢力によって生じる摩擦力によって、ヒンジ軸805を軸として第1の部材801と第2の部材802の相対的な動き(開いたり閉じたりするヒンジの動き)は規制される。一方、この摩擦力に打ち勝つ外力が働けば、ヒンジを閉じたり広げたりすることができる。このロック機構を利用することでも、図1の板状部材103の展開状態の維持(ロック)を実現することができる。   According to this structure, the first member 801 and the second member 802 are locked at an arbitrary opening angle. That is, the coil spring 806 tightens the adjacent cylindrical members 803 and 804 from the outside in the radial direction and biases the first member 801 and the second member 802 from the inside to the outside. The relative movement of the first member 801 and the second member 802 (the movement of the hinge that opens and closes) about the hinge shaft 805 is restricted by the frictional force generated by the tightening force and the urging force. On the other hand, if an external force that overcomes this frictional force is applied, the hinge can be closed or expanded. By using this locking mechanism, it is possible to maintain (lock) the expanded state of the plate-like member 103 in FIG.

以上が、開いた状態を維持するロック機構をヒンジが備え、このロック機構によりトノカバーの板状部材の展開状態を維持させ、垂れ下がりが生じないようにした例である。   The above is an example in which the hinge is provided with a lock mechanism that maintains the open state, and the unfolded state of the plate-like member of the tonneau cover is maintained by this lock mechanism so that no drooping occurs.

2.第2の実施形態
次に図1に示す構造において、第1の板状部材103aと第2の板状部材103bとを水平に維持する手段として、第1の板状部材103aから第2の板状部材103bの下側に差し出された支持部材によって、第2の板状部材103bを支え、それが垂れ下がらないようにする構造を説明する。
2. Second Embodiment Next, in the structure shown in FIG. 1, the first plate member 103a to the second plate are used as means for maintaining the first plate member 103a and the second plate member 103b horizontally. The structure which supports the 2nd plate-shaped member 103b with the supporting member extended to the lower side of the shaped member 103b, and prevents it from drooping is demonstrated.

図10は、図1に示す構成における板状部材の別形態の一例を示す上面図(A)および側断面図(B)である。まずこの例において、第1の板状部材103aと第2の板状部材103bとは分離しておらず、またヒンジにより連結された構造ではない。すなわち、第1の板状部材103aを構成する第1の板材904aと、第2の板状部材103bを構成する第2の板材904bとが、布906で覆われて周囲および折り目905の部分で縫製され、折り目905の部分で折り曲げ可能な構造とされている。この構造では、折り目905の部分がヒンジとしての機能を果たしている。なお、布906を樹脂材料で構成し、縫製の代わりに布906を高周波ウェルダー等で溶着してもよい。また、縫製の代わりに布906を接着剤で接着してもよい。   10 is a top view (A) and a side sectional view (B) showing an example of another embodiment of the plate-like member in the configuration shown in FIG. First, in this example, the first plate-like member 103a and the second plate-like member 103b are not separated and are not connected by a hinge. That is, the first plate member 904a constituting the first plate-like member 103a and the second plate member 904b constituting the second plate-like member 103b are covered with the cloth 906 at the periphery and the fold 905 portion. The structure is sewn and bendable at the fold 905 portion. In this structure, the portion of the fold line 905 functions as a hinge. The cloth 906 may be made of a resin material, and the cloth 906 may be welded with a high-frequency welder or the like instead of sewing. Moreover, you may adhere | attach the cloth 906 with an adhesive agent instead of sewing.

また、第1の板材904aに軸902によって平板形状の支持部材901が、板材の面に平行な面内で回転可能な状態で取り付けられている。図10には、支持部材901を第2の板状部材103bの方向に突出するように回転させた状態が示されている。この状態では、第1の板材904aに取り付けられた支持部材901によって、第2の板状部材103bの下面が支えられ、第2の板状部材103bが重力によって下方に折れ曲がらないようにロックされる。なお、第1の板状部材103aおよび第2の板状部材103bの支持部材901に対向する部分は、窪んでおり(符号907の領域)、板状部材103の下面に飛び出した部分が形成されないように工夫されている。   Further, a flat plate-like support member 901 is attached to the first plate member 904a by a shaft 902 so as to be rotatable in a plane parallel to the plate member. FIG. 10 shows a state in which the support member 901 is rotated so as to protrude in the direction of the second plate member 103b. In this state, the lower surface of the second plate member 103b is supported by the support member 901 attached to the first plate member 904a, and the second plate member 103b is locked so as not to be bent downward due to gravity. The Note that the portions of the first plate-like member 103a and the second plate-like member 103b facing the support member 901 are recessed (region 907), and the portion protruding to the lower surface of the plate-like member 103 is not formed. It has been devised.

図10に示す状態から、支持部材901を回転させ、支持部材901を第1の板状部材103aの下面側に収めると、第2の板状部材103bを下側から支持する構造が無くなり、第2の板状部材103bは折り目905の部分から下方に折り曲げることができる。こうして、板状部材103を図1(B)や図2(C)に示すように折り畳むことができる。   When the support member 901 is rotated from the state shown in FIG. 10 and the support member 901 is stored on the lower surface side of the first plate-like member 103a, there is no structure for supporting the second plate-like member 103b from the lower side. The second plate-like member 103b can be bent downward from the fold 905 portion. In this way, the plate-like member 103 can be folded as shown in FIG. 1 (B) or FIG. 2 (C).

本実施形態の変形として、板状部材103を展開した後に、骨となる部材を板状部材103の内部に入れ、水平な形状を維持するようにすることもできる。また例えば、第1の板状部材103aから第2の板状部材103bの下面方向に板状の支持部材を直線的に移動させ、第2の板状部材103bを下方から支え、展開状態における第2の板状部材103bの垂れ下がりを防止する構造を採用することもできる。以下、この態様の一例を説明する。図11は、第2の板状部材103bを支える構造の一例を示す断面図である。   As a modification of the present embodiment, after the plate-like member 103 is deployed, a member that becomes a bone can be placed inside the plate-like member 103 to maintain a horizontal shape. Further, for example, the plate-like support member is linearly moved from the first plate-like member 103a toward the lower surface of the second plate-like member 103b, and the second plate-like member 103b is supported from below, and the second plate-like member 103b in the unfolded state is supported. It is also possible to employ a structure that prevents the second plate-like member 103b from hanging down. Hereinafter, an example of this aspect will be described. FIG. 11 is a cross-sectional view showing an example of a structure that supports the second plate-like member 103b.

この例では、図11に示すように、第1の板状部材103aの下面に板状の支持部材910を収納する収納部911が設けられている。収納部911の内側は、強度を確保した補強構造912とされている。なお、図10と同じ符号の部分の構成は、図10に示すものと同じである。   In this example, as shown in FIG. 11, a storage portion 911 for storing a plate-like support member 910 is provided on the lower surface of the first plate-like member 103a. The inside of the storage portion 911 is a reinforcing structure 912 that ensures strength. In addition, the structure of the part of the code | symbol same as FIG. 10 is the same as what is shown in FIG.

図11(A)に示すように、第1の板状部材103aの下面側に収納された板状の支持部材910を第2の板状部材103bの方向に突出するように直線的にスライドさせることで、支持部材910によって第2の板状部材103bを下方から支え、第2の板状部材103bの下方への垂れ下がりが防止される。折り畳む際は、図11(B)に示すように、支持部材910を第1の板状部材103aの収納部911内に収納する。この状態で、第2の板状部材103bを下方に折り曲げることでき、第1の板状部材103aと第2の板状部材103bとを折り畳み、重ねることができる。   As shown in FIG. 11A, the plate-like support member 910 housed on the lower surface side of the first plate-like member 103a is linearly slid so as to protrude in the direction of the second plate-like member 103b. Thus, the second plate member 103b is supported from below by the support member 910, and the second plate member 103b is prevented from drooping downward. When folding, as shown in FIG. 11B, the support member 910 is stored in the storage portion 911 of the first plate-like member 103a. In this state, the second plate-like member 103b can be bent downward, and the first plate-like member 103a and the second plate-like member 103b can be folded and overlapped.

3.第3の実施形態
第2の実施形態で一例を説明した支持部材による板状部材の展開状態を維持する構造を第1の実施形態で例示した板状部材の構造に適用することもできる。すなわち、図1および図2に示すヒンジ104によって連結された第1の板状部材103aと第2の板状部材103bとを備えた構造において、図10や図11に示す支持部材によって、第2の板状部材103bを支える構造とすることができる。この場合、ヒンジ104は、展開状態をロックするロック機構を備えていても良いし、備えていなくても良い。
3. Third Embodiment The structure for maintaining the unfolded state of the plate member by the support member described as an example in the second embodiment can also be applied to the structure of the plate member exemplified in the first embodiment. That is, in the structure including the first plate member 103a and the second plate member 103b connected by the hinge 104 shown in FIGS. 1 and 2, the second support member shown in FIGS. The plate-like member 103b can be supported. In this case, the hinge 104 may or may not include a lock mechanism that locks the deployed state.
